Mayor de Blasio signed a law Tuesday requiring diaper changing stations be made available to men as well as women in new or newly renovated buildings.

The law is meant to address the dearth of changing stations in men’s restrooms.

“The way our society has organized things, it’s a message to men to not do their fair share,” de Blasio said. “Today is a day to celebrate the idea that all caretakers need to be respected, that all caretakers need to be able to do this precious work.”

De Blasio and his wife Chirlane McCray reminisced about how Hizzoner once changed diapers wherever he could, even on the hood of their old blue Ford Taurus.

“I can tell you I changed a lot of diapers. I do not look back on it nostalgically,” he said during the City Hall bill signing. “I cannot tell a lie and say I carried as much of the load as Chirlane. Thank you, honey.”
